You want to create a uniform (constant and parallel) magnetic field in a small volume of space. The field should be 500 Gauss. You can get a current of 0.8 Amperes from a power source, and you must choose one of the following methods (only one method is correct):
a. A single long straight wire, at distance r from the wire (what value of r is needed?)
b. In between two long parallel wires spaced distance 2D apart (what value of D is needed?)
c. A flat coil of radius R and N turns (suggest suitable values for R and N)
d. A long solenoid of length l and N turns (suggest suitable values for l and N)
Explain how you would get the required field by specifying the method and the physical dimensions needed.© BrainMass Inc. brainmass.com December 20, 2018, 2:50 am ad1c9bdddf
The magnetic field inside a long thin solenoid is quite uniform and parallel to the axis of the solenoid.
The magnetic field inside a long thin solenoid is given by:
B = mu*n*I
Where mu is the permeability, I is the ...
This is a discussion on how to create a uniform magnetic field.
